DIAGNOSIS. — Colony encrusting, autozooecia suboval, arranged in irregular longitudinal rows. Frontal shield coarsely perforated by 8 - 12 large excavations, each bowl-shaped with a broad smooth rim and the sides sloping to a smaller hole edged with several blunt denticles, these conferring a stellate appearance to each foramen. Peristomial aperture subcircular to transversely oval, with low rim; deeper interior proximal margin of aperture straight with tiny separated denticles along its edge. No oral spines. Small avicularian chamber on mid-distal rim of peristome; a larger avicularium situated suborally at one corner of the aperture, the rostrum long, acute, directed laterally, no crossbar or pivots. No ooecia observed.

REMARKS Recent Anarthropora monodon Busk, 1860 (type species) differs in having a much more densely foraminate frontal shield and smaller peristomial avicularia.

This dataset contains the digitized treatments in Plazi based on the original journal article Zágoršek, Kamil, Gordon, Dennis P. (2014): Revision of the Oligocene bryozoan taxa described by Stoliczka (1862), with the description of a new genus of Bryocryptellidae. Geodiversitas 36 (4): 541-564, DOI: 10.5252/g2014n4a3, URL: http://dx.doi.org/10.5252/g2014n4a3

ABSTRACT

A collection of bryozoans from the Oligocene of Latdorf, Germany, first described by Ferdinand Stoliczka in 1862 and not examined since, has been reexamined. Stoliczka had recognized 47 species, 24 of them new. Of these latter, 14 names remain valid; the remainder are synonyms of previously described taxa or, owing to the originally inadequate state of the fossil material examined, taxonomically indeterminable. Ŋe genera Orbitulipora Stoliczka, 1862 and Stichoporina Stoliczka, 1862, both introduced by Stoliczka in 1862 along with their type species, are still valid. Two of his species, one of which had not been examined since its first description, comprise a new bryocryptellid genus, Stoliczkella n. gen., which superficially resembles the celleporid genus Galeopsis Jullien & Calvet, 1903. Diagnoses or descriptions are provided herein for all of the taxa in the collection and lectotypes selected. Ŋe results of this revision will be applied to a forthcoming analysis of a recent extended excavation of the Latdorf section by the University of Leipzig, in which bryozoans are among the most abundant fossil groups.
